Abstract

"APARELHO PARA MEDIçãO DAS PROPRIEDADES DE UMA FIBRA óTICA". é revelado um aparelho para medição de propriedades de uma fibra de guia de onda ótica. O aparelho é livre de aberturas, lentes, e espelhos usualmente requeridos na medição de certas propriedades de fibra de guia de onda. O aparelho emprega uma comutação ótica na extremidade de lançamento da fibra ótica a ser testada, e outra comutação ótica na extremidade de saída da fibra ótica a ser testada. As comutações preservam a distribuição de energia de modo, particularmente o tamanho de ponto, de passagem de luz através destas. O aparelho pode ser usado para medir largura de faixa ou atenuação de uma fibra de guia de multimodo, ambas das quais são afetadas pela distribuição de energia de modo lançada e detectada."APPARATUS FOR MEASURING THE PROPERTIES OF AN OPTICAL FIBER". An apparatus for measuring the properties of an optical waveguide fiber is disclosed. The apparatus is free of apertures, lenses, and mirrors usually required to measure certain waveguide fiber properties. The apparatus employs an optical switch at the launch end of the optical fiber to be tested, and another optical switch at the output end of the optical fiber to be tested. The switches preserve the energy distribution so that, particularly the point size, light passes through them. The apparatus may be used to measure bandwidth or attenuation of a multimode guide fiber, both of which are affected by the released and detected mode power distribution.
